I live in a place where we have a Tesco mall with a big parking lot nearby, but then I have to walk a path through a green area with mostly grass, but some trees and bushes as well. The temperature difference is staggering. In hot summer, the parking lot is unbearable and the green area feels much better. In early spring/late autumn, the parking lot is uhm-okay (though still ugly), while walking through the green area gives you shivers: cool and wet wind. Only in deep winter, during the freezing days, both areas feel the same.
